T O ALL WIIOM IT MAY CONCERN: 4

vBe it known that I, ISAAC CRUM, of West Chester, in Butler county, Ohio, have invented anew end useful Improvement in IInrrows; and I do hereby declare that the following is auexact and full description thereof, reference being had to the accompanying drawings, and to the letters of reference markedthereon.

Figure 1 represents a top view of my herrow adjusted to be used.

Figure 2 represents a front view of the same in its folded position, and elevated upon' its sled.

Figure 3 represents u side view of the central portion or division of the borrow, and the sled with which it is connected. l

The object of my iuventionis te so construct the sectional hinged barrow, in connection with a sled, that the harrow may bc easily elevated upon the sled for transportation, as hereinafter fully described.

The three sections A B C :tre made in the usual form of the rectangular barrow, and are hinged together by eye-bolts und rods D E F, the two latter extending through the rztls ofthe divisions A B C, and tlie former serving as the hinge-pivot. '.Ihese hinges nrc arranged near the divisions A and C, so es to permit these two sections to be folded upon the central division or'harrow B. Instead of connecting the rails a et a ofthe several borrows together by the slats b b b, which are inserted in mortises, I propose to connect the rails by means oi' two double-hinged vstraps or bars of iron, to which the ruils a a a, ite., willbc'boltcd. By this meu-ns the sluts` b I will be dispensed with, und the hinged bars 'will also serve'in place of the eye-bolts and rods D E F. The sled 1I is combined with the central division of harrow, as represented in tig. 3, and it muy be elevated so that its weight shall rest upon the' herrow, und it muy be let down upon the ground and the harrow elevated, as' represented in iig. IZ. For the purpose of elevating und of lowering the harrow, the lever G and'double bracket d tl are provided. The two brackets Z d are fastened to the central rails of the middle hnrrow I3, and extend upwairds, and nre connected together by cross-ties o o A metal loop, t', is fastened to the front cross-beam oi the sled, and u stud, n, projects upwards from` the reairinost slut ot' the central barrow, es represented in the drawings. When the harrow is elevated, the leverl Gr is insert-ed in the position :ts seen in iig. 2, with its front end within the loop z', and the link connected with the rear end ot" the lever slipped upon a short stud, which projects from the renrmost slot or boum n: of the sled; and as the' lever rests upon the beams yz oi the sled,

:tud occupies u position'benezfth the lower cross-te o oi' the double bracket d cl, connected with the harrow, it of course will be held up out ot' content with the ground. When the sled is elevated above the barrow-teeth, the lever G will occupy the position as represented in figng, and a pin muy be inserted above it in the stud n. i

It will be seen thnt herrews constructed in accordance with my improvements can be transported from pluee to 4plu-ec without the eid ol' nny conveyance besides the sled, which constitutes a part of the structure. rIhe dilliculties und dangers attending the lending of the hnrrow upon a wagon are wholly avoided,.n.s it is but the labor ol' a single person (who may be :i youth ot' merelysutiicient ability to drive the tenui) to lend und fold the h-.trrow in position for transportation.. The red dotted lines in 1, represent the stretcher-chains to which the tenm will be connected er hitched, to draw the burrow diagonally over the ground to be borrowed. But

i when the hurl-ow is to be moved from place to pluce, the teem will be hitched to t-hc Central metal loop M, and

the stretcher muy be lont-lcd upon the hnrrew or sled.

lInving fully/described my invention, whut I claim, and desire to secure ny Letters Patent, is- 'lhe combinution of the hut-row lt with the sled I-I andr the ndjListing-mechanism 2', d, G, or its equivalent, :i-rrztnged und operating substnntiullj' ns and for the purpose described. i

In testimony whereof, l have hereunto set my hand, this 1st dny of October, A. D. 1867.
